Though she had an engagement and performances from A-listers like Rihanna, Jennifer Lopez and Aerosmith to compete with, the 59-year-old generated plenty of buzz of her own on the red carpet when she showed off a noticeably slimmer figure.

Prior to heading inside the show, Khan flaunted her tiny waist in skinny-fit printed pants, and a black satin blouse.

During her performance, the Queen of Funk took it up another notch, donning a brown, sequined catsuit to perform a medley of her hits, including "Ain't Nobody," "Through the Fire," and "I'm Every Woman."
